SustainUS is a nimble and innovative non-profit, accomplishing many great things all through the efforts of committed volunteers. I attended the UN Rio+20 Earth Summit with the group, and I was blown away by the passion, dedication, and brilliance of my fellow SustainUS delegates. I don't know of any other organization in the US that allows for young people to engage with the international policy process so deeply and in such an impactful way. Because of my amazing experience with SustainUS at Rio+20, I plan to stay involved with the organization for many years.
